I was wondering how common this is.  Since part of the libESMTP
philosophy was to eliminate the need for workstations to have to
run an MTA, I guess its consistent that it should not force the
use of inetd either.

I will probably do it for the sake of completeness, the idea has
been in the background for a while.  The question is more when.

Right - 0.7.0 adds an API smtp_recipient_check_complete() to query if
a given recipient of a message is complete, i.e. a subsequent call to
smtp_start_session() would not attempt to send the message to that
recipient.  Complete means success or permanent failure.

This can be used in handle_successful_send() to determine which
recipients must be retried later.  If these were listed in a header
present in outbox messages, say X-Balsa-Unsent: this could be
used to generate a recipient list when trying to send the message
again.  If someone can point me to the libmutt APIs to add or change
a header, I'll add some code to do this.
